    i find its always good to do a battery calibration after installing a new version of ios - not really sure why but sometimes the new ios can not get the calibration right until you recalibrate it

    Ditto- I've had to have mine plugged in at my desk today... I left for lunch with an 87% charge and when I came back it was down to 56% (approx. 1 hr) and very hot. I had some battery drain initially with the 4s, but never this severe.

    Yes.  I also have an iphone 4 and have noticed reduced battery life.  Not sure what is draining my battery but it definitely is not lasting as long.

    don't update the software ios 6 is not delivering what apple stated (improved battery life amongst others). My biggest mistake ever was updating and now my 4s is not meeting the required tech specs apple quotes on their website. DON'T UPDATE ! ! ! IT'S NOT WORTH THE HASSLE

    I updated to ios 6 on my 4S by doing a restore/update then restored from backup, and my battery life has increased along with signal strength , same results on my wifes 4S... not sure why some of you are having issues but if you are i suggest backing up your phone then restore/update then restore from backup, see if that helps ...

    If you check the Usage time vs. the Standby time, are the two numbers almost the same?

    I've updated as a new device, and restored from backup 2 times each way

    I've reset network settings (to try and get some signal bars back that have gone down to 1 almost everywhere)

    I've turned off and on the "Prevent iphones from automatically synching"

    I've turned Siri off

    I've turned auto time off

    I've turned all the location services off

    I've deleted 95% of the apps on the device

    Not much else to do besides take it in for a replacement

    iPhone 4, updated to iOS 6 this morning with the phone plugged in and charging.  Unplugged it at 7:30 this morning when the update was done, battery then at 100%.  Checked email a couple times this morning, didn't make any calls, put the phone in standby.  Dead at 4:30 in the afternoon.

    Upgraded two iPhone 4s units from iOS 5 to 6.  Battery on both now depletes in 2-3 hours using 3G network as well as WiFi.  Prior to the upgrade the battery would last a day or more.

    iPhone 4 updated to iOS 6 last night.  Charged over night, and have been playing music, sending multiple emails, making calls, played a few rounds of Solitaire, and checking out the new iOS features -- typical activity for me, aside from going through several of the new features.

    My results?  It's 6pm and my battery is at 63% -- quite normal IMO.  The point of me stating this is not to rub it in your faces, but to point out that (a) not all users are having battery issues with iOS 6, and (b) poor performance could be due to a botched iOS installation.


    I did my iOS update the way I always do -- by downloading the file to iTunes first without installing it, then install it on the iPhone from iTunes.  If you did an OTA update, I would not be surprised if something went awry, though it should work.  For those having battery problems, try downloading iOS to your computer and restore your iPhone.  As a last resort, you may have to restore and not load your backup -- a pain, I know, but that's what it might take.

  • man02195 Level 1 (0 points)

    Interesting, all 4 of my installs have been using iTunes downloaded file.

    2 restored from backup, 2 from clean installs

    Last one was from backup, and is best so far, only down 7% in one hour of idle

    Waiting impatiently for 6.0.1

  • rockmyplimsoul Level 5 (6,774 points)

    Oh, and wi-fi is on (though data usage has largely been over 3G) and Bluetooth on and used for ~10 minutes of phone calls.

  • waterrats Level 1 (0 points)

    I went to sleep last night at 12:15am and my phone was at 30% battery life.  I made sure I closed all applications to make sure nothing was beging used overnight.  I woke up at 5:50am (thats only 5.5hours) and my battery was already down to 18%.  I have now been up for 30 minutes with minimal use and I am now at 10%.  Only apps open are Mail, Scramble Free (played one game today), Safari (pulled the weather forecast once this morning), and Facebook (looked at one post).  Not heavy usage and yet my battery is depleting.  No way can I make it through the day anymore without charging it. 

  • man02195 Level 1 (0 points)

    I'm down to 57% already, at 10am, with 5.1.1 I was down to about 90% at this time

    Hurry up with 6.0.1

  • LonMan Level 1 (0 points)

    Since I updated yesterday - there is only one way to describe my battery life - *****........


    I am sure Apple will send an update to correct this as always!   (-:
